Palm Warbler

 Late every spring warblers invade Minnesota. Starting typically in late April and running through the first few week of May warblers stop by on their way migrating north. How long that they stay depends n the weather. In years where we have an early spring they hardly stop at all but in years where winter lingers we can see them for a week or two. Last winter was a great year for photographing warblers. Winter lasted very late and when the warblers came through in May they stayed for a while because their were no insects to eat further up north. The late winter also meant that the trees had not leafed out yet which makes the warblers much easier to see. This year has the possibility of being another good year for warblers watching. We have had some warm days lately which has some of the trees budding but a cold snap this week with a possibility of a little snow might help slow things down just enough for us to et a good warbler showing this year.

One of the earlier species to come back through are the palm warblers. The reason that they are one of the first back is because they do not winter as far south as most warblers. They typically winter in the southern U.S and Caribbean, while most species of warblers head down to Central and South America for the winter. Palms breed in northern Canada. They are found mostly in the eastern half of North America. I often hear palm warblers before I see them. Instead of flitting around in the trees like most warblers they are usually foraging through the leaf litter, like a fox sparrow, looking for insects and seeds.
